The eight turned on 90 ° for the first time was used for designation of infinity by the English mathematician John Wallace in the treatise published in 1655. You will not find such sign on the keyboard, but in code tables of the symbols used by the computer, it is provided. Therefore there are also ways for an insert of this sign in the majority of text and hypertext documents.
Instruction
1. Do not try to insert an infinity sign into text documents which are stored in files with the txt expansion. Alas, the format of such documents is calculated on work only with the first 128 symbols of the code tables used by the computer, and the symbol of infinity is placed much further.
2. Use code 8734 for an insert of this symbol in text documents which can display the symbols included in Unicode table. Install the input cursor in that position in the text where there has to be an infinity sign, and press the Alt key. Holding this key, type the code on the digital (additional) keyboard, and then release Alt, and the infinity sign will appear in the text.
3. In the Microsoft Office Word word-processor except the decimal code of a symbol of infinity provided in the previous step it is possible to use also its hexadecimal equivalent 221E (E is the English letter). Take him in the right place of the text, and then press a combination of the Alt and X keys - the word-processor will replace these four symbols with one infinity sign.
4. To keep in memory decimal or hexadecimal codes not really conveniently therefore in Microsoft Word application it is better to use the drop-down list of symbols placed in the Insert tab - look for it in group of teams extreme on the right. Twenty last symbols from recently used are included in this list therefore the first time you should use the full version of the table of symbols. Open it, having chosen the line "Other Symbols" in a drop-down list. In the field "Set" establish "mathematical operators" value, click an infinity symbol in the table of symbols and press the Insert button.
5. In hypertext documents about Unicode coding use symbolical primitives of the HTML 4 language for display of non-standard signs. For a conclusion to the page of an infinity sign it is necessary to place character set & infin in its source code;. It is possible to use also the hexadecimal code of this sign - character set & #8734; will display the same infinity sign on the hypertext page.
